BOILER AND PIPE COVERING.

SPECIFICATION formingpart of Letters Patent No. 246,059, dated August23, 1881.

Application filed March 8, 1881.

To all whom it may concern:

Be it known that I, ELEAZER AINSWORTH, of Wilmington, New Castle county,Delaware, have invented a new and useful Improvement in Boiler and PipeCoverings of which the following is a specification.

The invention consists in the composition and covering for boilers,steam-pipes, and condoctors, made and applied as hereinafter described.

In the accompanying drawing, the figure illustrates, in section, themanner of applying my improved heataetaining covering.

The first coating, A, placed upon the pipe or boiler B, is formed of amixture of clay, preterably talcose schist and thefibrons refuse fromtleshing, scouring, and trimming after liming or unhairing, and in thefinishing of skins in the manufacture of morocco, known as moroccoshavings, in about the proportion of three-fourths in bulk of the clayto one-fourth of the fibrous refuse or shavings, the same to be mixedwith sufficient quantity of water to make the mass plastic and adhesive.Around this coating is wrapped the wire a. The next coating, 0, iscomposed of a mixture of the fibrous waste from paper-mills or wood-pulpmills, clay, (talcose schist,) and lime in about the proportions of,say, one-half in bulk of the paper-mill or Wood-pulp-mill waste,one-quarter clay and one-quarter lime, also to be mixed with sufiicientwater to make the same plastic and adhesive.

(No model.)

This coating is then bound around with the wire-netting c, or it may bewound with wire, the same as the first coating. The third and finalcoating, 1.), is of the same material as coating (3.

In making and applying the covering compound I prel'er to follow themethod above described; but it is obvious that in the first and in allof the coatings the waste from woodpulp and paper mills might be mixedwith the morocco shavings and the clay or other waste material and notdepart from the spirit of my invention.

By thismeans an efficient heat-retainingcovering for boilers andsteam-pipes is made from what is now entirely naste material, and istherefore very inexpensive.

Having thus described myinvention, Iclaim as newand desire to secure byLetters Patent The boiler-covering herein shown and described, formed ofthe layer A, composed of a mixture of morocco shavings and clay, and thelayers G and D, composed of a mixture of paper-mill refuse or wood-pulpmill refuse and clay and lime, the layers A and 0 being held by the wirewrapping a and c, substantially as set forth.

ELEAZER AINSWORTH.
